' UNITED STATES PATENT QFFICEQ CHARLES IV. HUNT, OF WEST NEW BRIGHTON, ASSIGNOR TO THE C IV. HUNT I COMPANY, OF NEW YORK, N. Y.

COAL-CONVEYlNG APPARATUS.

SPECIFICATION forming part of Letters Patent No. 349,309, dated September 21, 1886. Application filed June 4, 1886. Serial No. 204,119. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES WV. HUNT, of West New Brighton, in the county of Bichinond and State of New York, have invented an Improvement in Apparatus for Conveying and Discharging Coal and other Material, and Automatically Returning the Car, of which the following is a specification.

In Letters Patent No. 127,885, dated June 11, 1872, and No. 147,400, dated February 10,

1874, I have set forth an apparatus in which the loaded car runs down on an inclined railway, and its inertia is arrested by' a crosshead upon a rope, against which cross-head the car acts, and there is a weight that is raised by this rope, and the descent of the weight automatically returns the empty car up the inclined railway.

My present invention is an improvement upon these devices, and it is made for lessening concussion, and for allowing the apparabus to assume its normal position without undue strain upon any of the parts.

I combine with the slightly-inclined track a wire rope passing around pulleys upon a traveling truck upon a second track, and fromthis a weight is suspended, the wire rope to which weight passes through between two pulleys suitably sustained in fixed positions, and upon the track-rope is a head-piece or bufi'er, against which the car acts as it runs down the incline, and in so doing gives motion to the rope that passes around the pulleys and is connected to the truck. weight hanging vertically belowthe truck, the truck itself commences to move with but little resistance, because the truck in rolling along the track moves the weight but little at first, and the lifting of the weight is accelerated by'the action of the truck as it rolls along, and draws the suspending'rope over one .of the pulleys, and as the leverage of the weight increases or overcomes the momentum of the car and stops the same. At this moment the coal or other material is discharged from the car, and the weight commences to descend and moves the parts in the opposite direction, giving motion to the empty ear, and the movement is accelerated as the weight descends and the car is projected up the inclined In consequence of the track to the place where it is again loaded. In this movement the truck will overrun the normal position, and it will partly raise the weight, and it will be returned to the normal position by the descent of the weight. In the drawings, Figure 1 is an elevation illustrating my improvements. Fig. 2 is a cross-section of the same, showing the truck in elevation; and Fig. 3 is a side elevation of the truck, track, and ropes, Figs. 2 and 3 being in larger size; and Fig. 4 is a View of a modification of the truck.

The railway A is at a slightly downward i11- clination sufficient for the car containing the coal or other material to run down freely, and

this track A is usually supported upon legs or frames 0 O, at the desired elevation above the surface upon which the coal or other material is to be discharged. There is a rope, D, preferably of wire, passing along the track and around sheaves at the respective ends of the track A, and upon this rope D is clamped a cross-piece or buffer, E, against which a jaw upon the railway-car comes into contact as the car approaches the place where the coal or other material is to be .delivered, and this erosspiece may be clamped at any desired place and its position changed from time to time to accommodate the place of delivcry of the coal or other material. The rope D, where it returns beneath the track A, passes to the truck-wheel K, the central part of which is a drum, around which the ropepasscs in opposite directions, and outside this drum are the flanged wheels K, that rest upon the trackbars B, that are near each other and below the tracks A, being supported by cross-pieces on the fra mes C O. From this truck K the bridlepiece It descends below the track B, such bridlepiece being made with holes at its upper ends, through which pass the shaft or axle of the truck K, and to the lower end of this bridlepiece is attached the chain or rope h' (preferably chain,) which passes down between the stationary sheaves L L, that aresnpported in the frame-work O", to the weight N. In some cases the wire rope It may pass around the pulley M and extend up again to the frame 0 where it would be firmly attached, as shown by dotted lines. The-weight N may be loaded 10o more or less to furnish the necessary resistance for overcoming the inertia of the full car, and for giving to the empty car an accelerated movement that will return it up the inclined railway-track to the place ofloading.

It is now to be understood that the present improvements are principally distinguishable from the devices heretofore made by the rope h passing between the stationary sheaves L L, because by this construction the truck is brought back to the same position after each movement, the sheaves L L guiding the rope 7: so that the lower part thereof and the weight only move vertically, while the upper part is drawn off at an angle in either one direction or the other, and the weight offers but little resistance to the movement of the truck when the car first acts upon the track-rope, because a large motion of the truck lifts the weight but little; but as the truck is moved further along the rope above the sheaves assumes a position more nearly in line with the movement of the truck, and the rope is drawn up as much as the truck is moved. By this improvement I am also enabled to use a pulley at the weight when required, so that the weight will only be raised half the distance the rope is pulled up, and this allows for using a heavier weight with less fall, so that the track need not be elevated so high. If the inertia carries the truck too far as the weight runs down, the weight will be again raised and stop the momentum of the truck and return it to the normal position. The drum K, around which the ropes pass, may be reduced to any desired diameter, and the operations will be the same, even it the ropes are simply connected to the frame or shaft of the truck, and in some cases the truck can be made to slide upon the track B, as illustrated in Fig. 4, instead of having wheels to roll upon the same.

I claim as my invention 1. The combination, with the inclined track and the rope D, of the track-bars I the truck with which the rope D is connected, the rope h, passing down from the truck, the weight suspended by such rope, and the stationary sheaves between which such rope passes, substantially as set forth.

2. The combination, with theinclinedtrack and the rope I), of the track-bars 13, a truck formed of two flanged wheels and an interme diate barrel around which the rope 1) passes, a bridle connected to the shalt oi the truckwheels, and a rope, l1, and weight suspended from such bridle, substantially as set forth.

3. The combination, with the inclined track and the rope D, of atruek with which the rope is connected, track-bars for said truck, a rope connected to the truck, two pulleys in fixed positions, between which the rope passes, a weight, and a pulley to such weight, around which the rope passes and is attached at its end to a fixed support, substantially as set forth.
